As two continental plates collide, the edges of the plates are crumpled and uplifted. Which of these landforms are MOST likely a result of this type of collision?
Normal faults
Mountain Ranges
U-shaped valleys
Shield Volcanoes
As early as the 1600's, scientists noticed that the continents appeared to fit together like pieces of a puzzle. The idea that the continents were once together and had drifted apart was not widely accepted. In the 1940'2 technology used on submarines led to evidence of continental movement. This technology allowed the scientist to do which of the following?
to explain the causes of continental movement
to determine fossil evidence of continental drift
to prevent further movement of continents
to reject theories of continental drift
Which of the following is a significant source of energy in Earth's interior?
Volcanos
Convection currents
Molten rock
Radioactive isotopes
